Delay management for distributed communications networks

Abstract

A method for programming the delay for a node in a communication system is disclosed. The node receives a selected delay value and a signal path delay value indicating a delay for signals communicated to the node. The signal path delay comprises an aggregation of transport delays calculated by each node for segments of the communication system between the node and a host node. The method further calculates an additional delay necessary to meet the selected delay value.

Description

Background technique [0001] Distributed antenna systems are widely used to seamlessly extend the coverage of wireless communication signals to locations not adequately served by traditional base stations, or to allocate capacity from a centralized radio suite. These systems generally include a host unit and a plurality of remote units. The master unit is typically coupled to a base station or between radio kits and multiple remote units. Each of the plurality of remote units includes one or more antennas that transmit and receive wireless signals on behalf of the base station or radio suite. [0002] A common problem in distributed antenna systems is to accommodate the different delays associated with each remote unit. Each remote unit is typically located at a different distance from the host. To allow the various antennas to be synchronized, a delay value is typically set at each remote unit. Unfortunately, conventional techniques for establishing delays for the various...

AI Technical Summary

Problems solved by technology

Unfortunately, conventional techniques for establishing delays for the various remote units add considerable complexity and / or cost to distributed antenna systems

For example, some common network synchronization techniques involve the use of various positioning technologies (e.g., Global Positioning System or GPS) that add further complexity and cost to operating these distributed antenna systems reliably and efficiently
